Fuel Pump - Toro Multi Pro 5700-D Service Manual

Fuel Pump

The fuel pump is attached to the frame just outboard of
the fuel injection pump (Fig. 40).
DANGER
Because diesel fuel is highly flammable, use cau-
tion when handling it. Do not smoke while testing
the fuel pump. Do not test fuel pump while engine
is hot. Make sure that there is adequate ventila-
tion when testing. Always wipe up any spilled
fuel before starting the engine.
Operational Test
1. Disconnect electrical connector from the fuel stop
solenoid to prevent the engine from firing (see Fuel Stop
Solenoid in this section).
2. Disconnect pump fuel discharge hose from the fuel
filter.
3. Make sure fuel hoses attached to the fuel pump are
free of obstructions.
4. Place pump discharge fuel hose into a large, gradu -
ated cylinder sufficient enough to collect 1 liter (33.8 fluid
ounces).
5. Collect fuel in the graduated cylinder by turning igni-
tion switch and holding it in the START position. Allow
pump to run for 30 seconds, then return switch to OFF.
6. Multiply amount of fuel collected in the graduated
cylinder by two (2) to get the capacity of the pump. Pump
capacity should be about 400 ml/minute (13.5 fluid
ounces/minute).
7. Replace fuel pump as necessary. Install fuel hose to
the fuel filter.
8. Wipe up any spilled fuel.
9. Reconnect electrical connector to the fuel stop sole-
noid.
